Abstract

The paper deals with the accompanying physical phenomena that arise in the process of cutting metal materials by abrasive water jet (AWJ) technology. The text describes the causes of arising vibration and acoustic emission, course of vibration and acoustic emission by analysing their frequency spectrum. Data were collected by touch sensors within controlled experiment, in which the AWJ technology for cutting alloy steel was used. During the experiments, some input factors were changed and measured parameters were subjected to different types of analysis using specialized software LabVIEW. Obtained data provide information about vibration and acoustic emission spectrum and enable us to find a dependency between the surface topography of cut materials and the emission spectrum of the accompanying physical phenomena arising during the AWJ process.
